Apparatus and method for creating three-dimensional personalized figure

Abstract

Disclosed herein is an apparatus and method for automatically creating a 3D personalized figure suitable for 3D printing by detecting a face area and features for respective regions from face data acquired by heterogeneous sensors and by optimizing global / local transformation. The 3D personalized figure creation apparatus acquires face data of a user corresponding to a reconstruction target; extracts feature points for respective regions from the face data, and reconstructs unique 3D models of the user's face, based on the extracted feature points; creates 3D figure models based on the unique 3D models and previously stored facial expression models and body / adornment models; and verifies whether each 3D figure model has a structure and a shape corresponding to actual 3D printing, corrects and edits the 3D figure model based on results of verification, and outputs a 3D figure model corresponding to 3D printing.

AI Technical Summary

Benefits of technology

Automatically generates refined 3D personalized figures suitable for 3D printing by detecting face features and optimizing transformations, accommodating various sensor inputs and ensuring model accuracy and safety for printing.

Problems solved by technology

In this way, among the conventional methods of creating a 3D face model, the scanning method requires a post-processing method conducted by an expert, and the existing sensor-based method is disadvantageous in that good results can be obtained only in a preset condition.

Further, since multiple cameras must be used, various disadvantages such as problems with synchronization between cameras, color coincidence, and geometric correction are present.

Furthermore, a problem arises in that appearance data generated by scanning the overall region of a head including a face or by capturing only a part of the face is composed of a large number of unrefined dummy meshes having holes or overlapping, or includes only a part of face data, and thus it is not suitable to directly apply the appearance data to 3D printing.
